Intraventricular hemorrhage treated with intraventricular fibrinolysis. A 10-year experience

Purpose We evaluate the results and complications of our intraventricular fibrinolysis protocol. Material and methods A retrospective analysis was made of the cases of intraventricular hemorrhage with 13-bed Intensive Care Unit. Graeb score 6 or above subjected to intraventricular fibrinolysis. We gathered demographic parameters, clinical risk scores, tomography data and case histories showing neurological status and complications related to intraventricular treatment. The results between those who died and the survivors were compared. Results Intraventricular fibrinolysis was performed in 42 patients (69% males) with intraventricular hemorrhage. The average age was 58.36 years (SD 16.67), with a median APACHE II score of 17.5 (r 3–29). A total of 16.7% were receiving acenocoumarol, and 7.1% were on antiplatelet drugs. The median Glasgow Coma Score at the start of treatment was 8 (r 3–13). The median Graeb score was 9 (r 6–12), and was severe (Graeb 9–12) in almost 62%. In turn, 26.2% of the patients developed ventriculitis, and there was further bleeding in 7.1%. Death occurred in 50% of the cases. None of the analyzed variables were significantly related to increased mortality. In the 21 survivors, the Glasgow Outcome Score at 3 months was 2 in 23.8% of the cases, 3 in 28.57%, 4 in 23.8% and 5 in 28.57% of the patients. Conclusions Intraventricular fibrinolysis does not appear to involve a high rate of complications, and may result in lesser mortality, with a better functional outcome after three months than that estimated and published in the literature in reference to intraventricular hemorrhage (AU)

Handling continuous renal replacement therapy-related adverse effects in intensive care unit patients: the dialytrauma concept.

Continuous renal replacement therapy (CRRT) is increasingly used for the management of critically ill patients. As a consequence, the incidence of complications that accompany CRRT is also rising. However, a standardized approach for preventing or minimizing these adverse events is lacking. Dialytrauma is a newly proposed concept that encompasses all harmful adverse events related to CRRT while providing a framework for prevention or, at the least, early recognition of these events in order to attenuate the consequences. A mainstay of this approach is the utilization of a dedicated checklist for improving CRRT quality and patient safety. In this context, we discuss the most important adverse effects of CRRT and review current strategies to minimize them.

[Variability in renal dysfunction defining criteria and detection methods in intensive care units: are the international consensus criteria used for diagnosing renal dysfunction?]. / Variabilidad en los criterios de definición y métodos de detección de la disfunción renal en las unidades de cuidados intensivos ¿se aplican los consensos internacionales para el diagnóstico de la disfunción renal?

OBJECTIVE: To evaluate variability in the detection and prevention of acute kidney injury (AKI) in the intensive care unit (ICU), and application of the international recommendations in this field (Acute Dialysis Quality Initiative [ADQI] and Acute Kidney Injury Network [AKIN]). DESIGN: A prospective, observational, multicenter study. SETTING: A total of 42 ICUs in 32 hospitals (78% in third level hospitals and 70.7% general units) recruited for a study on the prevalence of AKI (COFRADE). INTERVENTIONS: Survey. VARIABLES: Aspects related to AKI detection and prevention and renal replacement therapy protocols. RESULTS: The method used for estimating glomerular filtration rate was serum creatinine in 36.6%, creatinine clearance in 41.5% and equations in 22%; none reported using cystatin-C. Only 39.1% ICUs acknowledged the use of stratification systems (13 RIFLE and 3 AKIN). A total of 48.8% ICUs had no written protocols for AKI prevention, 31.7% reported using them only for contrast nephropathy, 7.3% for nephrotoxic drugs and 12.2% for both. In contrast, 63.4% participants had written protocols for renal replacement therapy, 70.7% had implemented a training program, and 53.7% had some method for adjusting doses of drugs when on renal replacement therapy. CONCLUSIONS: We observed important variability regarding diagnostic criteria and prevention of AKI in Spanish ICUs, the application of ADQI or AKIN recommendations still being low in our units. Renal replacement therapy seems to generate more concern among our intensivists than AKI management.

[Epidemiology of acute kidney failure in Spanish ICU. Multicenter prospective study FRAMI]. / Epidemiología del fracaso renal agudo en las UCI españolas. Estudio prospectivo multicéntrico FRAMI.

OBJECTIVE: Multicenter study oriented at establishing the incidence and prognosis of acute kidney failure (AKF) in the ICU of our country. MATERIAL AND METHODS: Prospective study of adult patients admitted over 8 months in 43 Spanish ICUs to detect AKF defined as creatinine>or=2 mg/dl or diuresis<400 ml/24 hours (in chronic patients 100% increase of creatinine, excluding those with baseline creatinine>or=4 mg/dl). RESULTS: 901 episodes of AKF (AKF episodes (incidence 5.7%), 55% of which occurred on admission. A total of 38.4% of the episodes were due to acute tubular necrosis (ATN), 36.6% to prerenal, and 21.2% to mixed. Renal depuration (RC) was required in 38%. Mortality was 42.3% during the AKF episode (34.1% in those who were admitted with AKF versus 50.9% in those who developed it after admission), 80% in patients with Hepatorenal Syndrome, 51.6% in ATN and 29.9% in prerenal. We detect an independent relationship with mortality for age (OR 1.03), background of diabetes (OR 2.06), development of AKF in the ICU (OR 2.51), oliguria (OR 5.76) and RC (OR 2.32). Recovery of the kidney function occurred in 85.6% of the survivors and RC was maintained in only 1.1% on discharge from the ICU. We calculated the area under the curve of APACHE II on admission (0.62), SOFA on onset of AKF (0.68), Liaño index (0.7) and maximum SOFA (0.79). CONCLUSIONS: AKF in ICU patients does not show an elevated incidence but does have high mortality, presenting greater seriousness when it appears after admission. However, recovery is elevated in patients who survive. The usual prognostic indexes are not exact in this patient group, the ISA and maximum SOFA being those which shows a closer relationship with mortality.

Objetivo. Estudio multicéntrico orientado a establecer la incidencia y el pronóstico del fracaso renal agudo (FRA) en las Unidades de Cuidados Intensivos (UCI) de nuestro país. Material y método. Estudio prospectivo de los pacientes adultos ingresados durante 8 meses en 43 UCI españolas para detectar FRA definido como creatinina ≥ 2 mg/dl o diuresis < 400 ml/24 horas (en pacientes crónicos aumento de creatinina del 100%, excluyendo aquellos con creatinina basal ≥ 4 mg/dl). Resultados. 901 episodios de FRA (incidencia 5,7%), de los cuales el 55% lo presentaban en el momento del ingreso. Fueron debidos a necrosis tubular aguda (NTA) el 38,4%, prerrenal el 36,6%, y mixta el 21,2% de los episodios. Precisaron depuración renal (DER) el 38%. La mortalidad fue del 42,3% durante el episodio de FRA (34,1% en los que ingresan en FRA, frente a 50,9% en los que lo desarrollan tras el ingreso), 80% en pacientes con síndrome hepatorrenal, 51,6% en NTA y 29,9% en prerrenal. Detectamos relación independiente con la mortalidad para la edad (OR 1,03), antecedente de diabetes (OR 2,06), desarrollo de FRA en la UCI (OR 2,51), oliguria (OR 5,76) y DER (OR 2,32). La recuperación de la función renal se produjo en el 85,6% de los supervivientes y en tan solo un 1,1% se mantenía la DER al alta de la UCI. Calculamos el área bajo curva del APACHE II al ingreso (0,62), SOFA al inicio del FRA (0,68), índice de Liaño (0,7) y SOFA máximo (0,79). Conclusiones. El FRA en pacientes de UCI no presenta una elevada incidencia pero sí alta mortalidad, presentando mayor gravedad cuando hace su aparición tras el ingreso. Sin embargo, en los pacientes que sobreviven, la recuperación es elevada. Los índices pronóstico habituales no son exactos en este grupo de pacientes, siendo el ISI y SOFA máximo el que muestra una relación más estrecha con la mortalidad
